Suggest me a [horror/thriller] book where the main character gets themselves into deeper trouble and there’s no turning back..

I just finished Pet Sematary, so spoilers ahead if you haven't read it because I'm about to talk about the ending.

I loved this book and gave it 5 stars (a rare rating for me haha). I really enjoyed the part of the story where Louis Creed got himself into a situation (digging up Gage's grave so he could bury him in the pet sematary] and he KNEW it was bad, and he knew there would be consequences, but he was at a point of no turning back and things just got worse and worse.

So I would love to read a book where that happens / is a main focus in the plot! I prefer a book in the horror, thriller, suspense, genre…I dislike romance, "chick lit", fantasy so if it's anything aside from those genres I'll be happy.

Thanks in advance!
